Participants

Reaction Steps

A suspension of 28.7 g (100 mmol) of 2,6-dibromoanthraquinone, 44.7 g (260 mmol) of 1-naphthylboronic acid, 89.2 g (420 mmol) of potassium phosphate, 1.8 g (6 mmol) of tri-o-tolylphosphine and 225 mg (1 mmol) of palladium(II) acetate in a mixture of 200 ml of dioxane, 400 ml of toluene and 500 ml of water is refluxed for 16 h. After cooling, the solid is filtered off with suction, washed three times with 100 ml of water each time and three times with 100 ml of ethanol each time, dried in vacuo and subsequently recrystallised twice from chlorobenzene. Yield: 41.6 g (90 mmol), 90.3% of theory; purity: 99% according to NMR.
